Best: Afterlame and Burning Bridges.
Will be the Best: Think Thank (Patchwork Patterns), Montreal (Sunset Films), or Flavor Country (Sandbox Films).
All snowboarding? Yes...I enjoy watching snowboard movies more at the moment, they have just progressed more and they get me more stoked in general...and you didn't say "ski movies." But if you are talking about ski movies, I seriously don't know what to say, I don't have a favourite ski movie, nor do I have an idea which one will be the best.
